Description

Dachanordnung mit Himmelelement Roof arrangement with sky element
Die Erfindung betrifft eine Dachanordnung eines Kraftfahrzeuges mit den Merkmalen des Oberbegriffs des Patentanspruchs 1. The invention relates to a roof arrangement of a motor vehicle having the features of the preamble of patent claim 1.
Eine derartige Dachanordnung ist aus der Praxis bekannt und bildet beispielsweise ein als Panoramadach ausgebildetes Festdach aus, welches mit einem transparenten Glasoder Kunststoff-Paneel versehen ist, durch das Umgebungslicht in einen Innenraum des betreffenden Kraftfahrzeuges einfallen kann. Das Glas- oder Kunststoff-Paneel weist eine umlaufende Randumschäumung auf, die insbesondere aus einem Polyurethanwerkstoff gefertigt ist und die zur Dichtung gegenüber angrenzenden Außenhautabschnitten genutzt werden kann. Des Weiteren umfasst die bekannte Dachanordnung einen Innenhimmel mit einem Himmelelement, das eine von dem Fahrzeuginnenraum sichtbare innere Sichtfläche der Dachanordnung bildet. Um der Dachanordnung an seiner Innenseite ein harmonisches Erscheinungsbild zu geben, grenzt das Himmelelement mit einem Rand an das Glas- oder Kunststoff-Paneel an. Die Fixierung erfolgt mittels einer Klammer, die an einem Gegenelement verrastet ist, welches mit dem Glasoder Kunststoff-Paneel verklebt ist. Hierfür sind spezielle Bauelemente erforderlich, was sich wiederum in den Kosten der Dachanordnung niederschlägt. Such a roof arrangement is known from practice and forms, for example, a fixed roof designed as a panorama roof, which is provided with a transparent glass or plastic panel through which ambient light can enter the interior of the motor vehicle in question. The glass or plastic panel has peripheral foaming around the edge, which is made in particular from a polyurethane material and which can be used for sealing against adjacent sections of the outer skin. Furthermore, the known roof arrangement includes an inner liner with a liner element that forms an inner visible surface of the roof arrangement that is visible from the vehicle interior. In order to give the roof arrangement a harmonious appearance on its inside, the sky element borders on the glass or plastic panel with an edge. It is fixed by means of a clip that is snapped onto a counter-element that is glued to the glass or plastic panel. This requires special components, which in turn is reflected in the cost of the roof assembly.
Eine Dachanordnung, die ein Dachpaneel mit einer Randumschäumung umfasst, ist beispielsweise aus der Druckschrift DE 101 55 170 B4 bekannt. A roof arrangement that includes a roof panel with an edge foam is known, for example, from publication DE 101 55 170 B4.
Der Erfindung liegt die Aufgabe zugrunde, eine gemäß der einleitend genannten Gattung ausgebildete Dachanordnung zu schaffen, welche sich durch eine vereinfachte Befestigung des Himmelelements an dem Festdachelement auszeichnet. Diese Aufgabe ist erfindungsgemäß durch die Dachanordnung mit den Merkmalen des Patentanspruchs 1 gelöst. The invention is based on the object of creating a roof arrangement designed according to the type mentioned in the introduction, which is characterized by a simplified fastening of the headlining element to the fixed roof element. According to the invention, this object is achieved by the roof arrangement having the features of patent claim 1 .
Gemäß der Erfindung wird also eine Dachanordnung eines Kraftfahrzeugs vorgeschlagen, die ein Festdachelement, das starr und nicht verlagerbar gegenüber einer Dachunterkonstruktion angeordnet ist und ein flächiges Glas- oder Kunststoff-Paneel umfasst, sowie einen Innenhimmel mit einem Himmelelement aufweist, das eine innere Sichtfläche bildet und an das Festdachelement angebunden ist. Das Festdachelement weist einen nach einem Schäumprozess oder Spritzgießprozess gefertigten Formabschnitt auf, der an das Glas- oder Kunststoff-Paneel angeformt ist und an dem eine Befestigungsgeometrie ausgeformt ist, an der das Himmelelement befestigt ist. An dem Festdachelement sind damit durch den Formabschnitt in direkter Weise Befestigungsmittel angeordnet, an denen das Himmelelement ohne Nutzung weiterer Befestigungsteile, wie Klammem oder dergleichen, fixiert werden kann. Das Himmelelement muss lediglich mit der Befestigungsgeometrie des Formabschnitts in Eingriff gebracht werden. According to the invention, a roof arrangement of a motor vehicle is therefore proposed which has a fixed roof element which is arranged rigidly and cannot be displaced in relation to a roof substructure and which comprises a flat glass or plastic panel, as well as an inner liner with a liner element which forms an inner visible surface and connected to the fixed roof element. The fixed roof element has a molded section produced by a foaming process or injection molding process, which is molded onto the glass or plastic panel and on which a fastening geometry is formed, to which the sky element is fastened. Fastening means are thus arranged directly on the fixed roof element by the shaped section, to which means the sky element can be fixed without using further fastening parts, such as clamps or the like. The sky element only has to be brought into engagement with the fastening geometry of the mold section.
Der Formabschnitt der Dachanordnung nach der Erfindung stellt grundsätzlich ein Kunststoffelement des Festdachelements dar, welches nach einem Formprozess, wie einem Schäumprozess oder einem Spritzgießprozess, gefertigt und damit in einer korrespondierenden Kavität eines Formwerkzeugs ausgeformt und in dem Schäumprozess oder Spritzgießprozess an das Glas- oder Kunststoffpaneel angeformt wird. Das Formwerkzeug zur Fertigung des Formabschnitts ist beispielsweise als RIM(Reaction Injection Molding)- Werkzeug ausgebildet. Vorzugsweise wird zum Ausformen des Formabschnitts ein Polyurethanwerkstoff eingesetzt. The molded section of the roof arrangement according to the invention basically represents a plastic element of the fixed roof element, which is manufactured according to a molding process, such as a foaming process or an injection molding process, and is thus formed in a corresponding cavity of a molding tool and molded onto the glass or plastic panel in the foaming process or injection molding process will. The molding tool for manufacturing the molded section is designed, for example, as a RIM (Reaction Injection Molding) tool. A polyurethane material is preferably used to form the mold section.
Der Kunststoff-Formabschnitt, der an dem Glas- oder Kunststoff-Paneel ausgeformt ist, kann umlaufend oder auch nur in definierten Bereichen des Festdachelements ausgeformt sein. Bei einem umlaufenden Formabschnitt kann die Befestigungsgeometrie in entsprechender Weise nur lokal oder auch umlaufend ausgebildet sein. The plastic molded section, which is formed on the glass or plastic panel, can be formed all around or only in defined areas of the fixed roof element. In the case of a peripheral shaped section, the fastening geometry can be configured in a corresponding manner only locally or also peripherally.
Bei einer speziellen Ausführungsform der Dachanordnung nach der Erfindung steht das Himmelelement mit der Befestigungsgeometrie in Eingriff, wobei das Himmelelement insbesondere in die Befestigungsgeometrie eingreift. Bei einer bevorzugten Ausführungsform der Dachanordnung nach der Erfindung umfasst die Befestigungsgeometrie eine Nut. Die Fixierung des betreffenden Himmelelements erfolgt durch Einbringen eines Himmelelementrands oder dergleichen in diese Nut. In a special embodiment of the roof arrangement according to the invention, the headlining element engages with the fastening geometry, with the headlining element engaging in particular with the fastening geometry. In a preferred embodiment of the roof arrangement according to the invention, the fastening geometry comprises a groove. The sky element in question is fixed by introducing a sky element edge or the like into this groove.
Um das Himmelelement ausziehsicher in der Nut fixieren zu können, weist die Nut bei einer speziellen Ausführungsform der Dachanordnung nach der Erfindung einen Hinterschnitt auf. In order to be able to fix the headlining element in the groove so that it cannot be pulled out, the groove has an undercut in a special embodiment of the roof arrangement according to the invention.
Um das Zusammenwirken zwischen der Befestigungsgeometrie des Formabschnitts und dem Himmelelement zu optimieren, ist es vorteilhaft, wenn das Himmelelement eine Befestigungsstruktur aufweist, welche in die Befestigungsgeometrie des Formabschnitts eingreift und welche komplementär zu dieser Befestigungsgeometrie ausgebildet ist. In order to optimize the interaction between the fastening geometry of the shaped section and the headlining element, it is advantageous if the headlining element has a fastening structure which engages in the fastening geometry of the shaped section and which is designed to complement this fastening geometry.
Beispielsweise umfasst die Befestigungsstruktur einen Randkeder, durch den eine Randaufdickung des Himmelelements realisiert ist, welche wiederum in die Nut, welche die Befestigungsgeometrie des Formabschnitts bildet, eingreift. For example, the attachment structure includes an edge piping, through which an edge thickening of the sky element is realized, which in turn engages in the groove, which forms the attachment geometry of the molded section.
Bei einer hinsichtlich Design hohen Ansprüchen genügenden Ausführungsform der Dachanordnung nach der Erfindung ist der Formabschnitt an einer Unterseite des Glasoder Kunststoff-Paneels angeordnet und dort formschlüssig an das Glas- oder Kunststoffpaneel angeformt. In an embodiment of the roof arrangement according to the invention that satisfies high design requirements, the shaped section is arranged on an underside of the glass or plastic panel and is formed there in a form-fitting manner on the glass or plastic panel.
Zweckmäßigerweise umfasst das Glas- oder Kunststoff-Paneel der Dachanordnung nach der Erfindung auch eine Randumschäumung, die vorzugsweise aus einem Polyurethanwerkstoff gefertigt ist. Die Randumschäumung und der Formabschnitt können in einem Fertigungsschritt in einem Formwerkzeug an das Glas- oder Kunststoff-Paneel angeformt werden, wobei insbesondere dann die Randumschäumung und der Formabschnitt aus dem gleichen Werkstoff geformt sein können. Expediently, the glass or plastic panel of the roof arrangement according to the invention also includes an edge foam coating, which is preferably made of a polyurethane material. The foamed edge and the shaped section can be molded onto the glass or plastic panel in one manufacturing step in a mold, and in particular the foamed edge and the shaped section can then be formed from the same material.
Der Formabschnitt, an dem die Befestigungsgeometrie für das Himmelelement ausgeformt ist, kann einstückig mit der Randumschäumung ausgebildet bzw. Bestandteil der Randumschäumung sein. Bei einer alternativen Ausführungsform der Dachanordnung nach der Erfindung ist der Formabschnitt zumindest bereichsweise von der Randumschäumung beabstandet. The mold section on which the fastening geometry for the headlining element is formed can be formed in one piece with the peripheral foam or can be a component of the peripheral foam. In an alternative embodiment of the roof arrangement according to the invention, the shaped section is spaced at least in regions from the edge foaming.
Das Festdachelement ist beispielsweise über eine Kleberaupe mit der Dachunterkonstruktion verklebt. Wenn zwischen der Randumschäumung und dem Formabschnitt ein Zwischenraum liegt, ist die Kleberaupe vorzugsweise in diesem Zwischenraum angeordnet. Dieser Bereich ist an der Innenseite der Dachanordnung durch den Innenhimmel verblendet und somit vom Fahrzeuginnenraum aus nicht sichtbar. The fixed roof element is glued to the roof substructure with a bead of adhesive, for example. If there is an intermediate space between the edge foaming and the shaped section, the bead of adhesive is preferably arranged in this intermediate space. This area is concealed on the inside of the roof arrangement by the roof liner and is therefore not visible from the vehicle interior.
Weitere Vorteile und vorteilhafte Ausgestaltungen des Gegenstandes der Erfindung sind der Beschreibung, der Zeichnung und den Patentansprüchen entnehmbar. Further advantages and advantageous configurations of the subject matter of the invention can be found in the description, the drawing and the patent claims.

Die Dachanordnung 10 umfasst ein Festdachelement 12, das starr und nicht verlagerbar gegenüber einer Fahrzeugkarosserie und gegenüber einer Dachunterkonstruktion angeordnet ist, sowie ein bewegliches Deckelelement 14, welches Bestandteil eines Dachöffnungssystems ist und mittels einer nicht näher dargestellten Verstellkinematik zwischen einer eine Dachöffnung verschließenden Schließstellung und einer die Dachöffnung zumindest teilweise freigebenden Freigabestellung verstellbar ist. Neben dem Festdachelement 12 und dem Deckelelement 14 umfasst die Dachanordnung 10 Dachseitenholme 16A und 16B, welche insbesondere im Bereich des Festdachelements 12 jeweils einen Lagerflansch 18 ausbilden, auf dem das Festdachelement 12 über eine Kleberaupe 20 aufliegt und der einer Dachunterkonstruktion zugeordnet ist. Alternativ kann die Dachordnung 10 ohne Dachöffnungssysteme ausgebildet sein, wobei dann vorzugsweise ein sich über die Fläche der Dachanordnung erstreckendes Festdachelement vorgesehen ist, das starr und nicht verlagerbar gegenüber einer Dachunterkonstruktion angeordnet ist. The drawing shows a roof arrangement 10 of a motor vehicle, which covers an interior of the motor vehicle and is therefore arranged above the seating area for vehicle occupants. The roof arrangement 10 comprises a fixed roof element 12, which is arranged rigidly and cannot be displaced in relation to a vehicle body and in relation to a roof substructure, and a movable cover element 14, which is part of a roof opening system and, by means of adjustment kinematics (not shown in detail), between a closed position that closes a roof opening and a closed position that closes the roof opening Roof opening at least partially releasing release position is adjustable. In addition to the fixed roof element 12 and the cover element 14, the roof assembly 10 includes roof side rails 16A and 16B, which each form a bearing flange 18, particularly in the area of the fixed roof element 12, on which the fixed roof element 12 rests via an adhesive bead 20 and which is assigned to a roof substructure. Alternatively, the roof arrangement 10 can be designed without a roof opening system, in which case a fixed roof element is preferably provided which extends over the surface of the roof arrangement and is arranged rigidly and cannot be displaced relative to a roof substructure.
Um der Dachanordnung 10 an ihrer dem Fahrzeuginnenraum zugewandten Innenseite ein optisch positiv anmutendes Erscheinungsbild zu geben, weist die Dachanordnung 10 einen Innenhimmel 22 mit einem aus einem aufspannbaren Stoff gebildeten Himmelelement 24 auf.
